Shot Calc helps trained industrial radiography personnel estimate gamma and X-ray exposure times. Use Ir-192, Se-75, or Co-60 reference values, enter points from your X-ray tube chart, calculate source decay and geometric unsharpness, or use field unit and pipe schedule tools.
The calculator is free, requires no account, and can be installed for offline use after an initial visit. Built-in reference data has been reviewed by SIS Level III. Results are planning estimates: verify them against approved charts and procedures. This app does not establish radiation safety boundaries or authorize exposures.
